People will have to wear masks on airplanes, trains, buses and at airports through Jan. 18, the Transportation Security Administration (TSA) told various media outlets in a statement Tuesday.
Why it matters: The mandate was set to expire on Sept. 13, but the highly contagious Delta variant has forced the federal government to change course on mask mandates.
What they're saying: "The purpose of TSA's mask directive is to minimize the spread of COVID-19 on public transportation," the statement reads.
The big picture: The Federal Aviation Administration (FAA) has received over 2,867 reports of passengers in violation of the federal mask mandate, per CNN.
